Title: Liquid crystal element
Inventor: TAKAO HIDEAKI
IPC: C08F20/32
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent orientation defects or faults in functions of the device constitution due to difference in the surface levels of a substrate and to obtain high-quality image display characteristics with uniform orientation of a liquid crystal by forming a flattening layer which contains a specified acryl polymer component having a repeating unit on a color filter. SOLUTION: At least color filters 5a to 5c and a flattening layer 7 on the color filters 5a to 5c are formed between one substrate and a transparent electrode 2a, 2b, and the flattening layer 7 contains an acryl polymer component having the repeating unit expressed by formula. In the formula, R is H or CH3 . Since a resin compsn. containing the acryl polymer component having the repeating unit expressed by the formula is used for flattening treatment of the substrates 1a, 1b having the structure above described, difference in the surface levels due to recesses between pixels and difference in the film thickness of the color filters 5a, 5c are largely corrected. Therefore, even when transparent electrodes 2a, 2b and orientation controlling films 3a, 3b are formed on the pixels, the substrate surface can be maintained almost flat.

Filed: 1985-09-26
Abstract: PURPOSE:To remove automatically variation in atmospheric pressure, secular changes of a pressure sensor and a pressure value converting circuit, etc., and to display the depth of water having no error by selecting a bathometer function before entry into water. CONSTITUTION:The output of the pressure sensor 1 when a bathometer function selection signal B is outputted is A/D-converted 3 and a detecting circuit 3 decides whether the converted pressure value is normal or not and stores the value as an initial pressure value in a storage circuit 4 when the value is normal. When the value is abnormal, on the other hand, the abnormality is displayed on a display device 9. Then when the storing operation of the circuit 4 is completed, the difference between the pressure value obtained by the A/D conversion 2 and the initial pressure value which is stored 4 is converted by a converting circuit 5 into the depth of water, which is sent to the display device 9.

Title: Variable displacement swash plate type compressor
Inventor: MATSUDA MIKIO
IPC: F04B27/08
Filed: 1990-08-10
Abstract: PURPOSE:To form a spring in small size by setting a projection area of a piston, by which the first operating chamber is formed, larger than the projection area of a piston of the second operating chamber. CONSTITUTION:Since a projection area of a piston 7 in a side of the second operating chamber 50, in which dead volume is generated, is set smaller than the projection area of the piston 7 in a side of the first operating chamber 60, a relatively small influence is given to the piston 7 by reaction force caused by the dead volume. Accordingly, tension of a spring 308 can be preset to a small value even in the case of arranging the spring 308 for compensating a fluctuation of the reaction force caused by the dead volume in the side of this second actuating chamber 50. In this way, the spring 308 can be miniaturized.

When the prescribed number of recording paper P is housed in the stack part 305, a feed is started.
